The philosopher asks, “Is the spherical glass half empty of half full?” You say, “I’m more into the math of it” and then you calculate the volume of water that appears halfway up (or down) in the glass. If the radius of the glass is 2 inches, what is the volume of the half-filled (or half-empty) glass?

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
